Mechanism of Cu-catalyzed aryl boronic acid halodeboronation using electrophilic halogen: Development of a base-catalyzed iododeboronation for radiolabeling applications

An investigation into the mechanism of Cu-catalyzed aryl boronic acid halodeboronation using electrophilic halogen reagents is reported. Evidence is provided to show that this takes place via a boronate-driven ipso-substitution pathway and that Cu is not required for these processes to operate: General Lewis base catalysis is operational. This in turn allows the rational development of a general, simple, and effective base-catalyzed halodeboronation that is amenable to the preparation of 125I-labeled products for SPECT applications.

Pharmacologically tested aldose reductase inhibitors isolated from plant sources – A concise report

Aldose reductase (AR), a cytosolic, monomeric oxidoreductase, is a key enzyme in the polyol pathway which controls the conversion of glucose to sorbitol. The accumulation of sorbitol by the activation of AR enzymes in lens, retina, and sciatic nerves leads to the cause of diabetic defects resulting in various secondary complications, viz. retinopathy, neuropathy, nephropathy and Alzheimer’s disease. Thus, reduction of the polyol pathway flux by AR inhibitors could be a potential therapeutic opening in the treatment and prevention of diabetic complications. At present, the AR inhibitors belong to two different chemical classes. One is the hydantoin derivatives, such as Sorbinil, Dilantin, and Minalrestat, and the other is the carboxylic acid derivatives, such as Epalrestat, Alrestatin, and Tolrestat. However, it is known that most of these synthethic compounds have unacceptable side-effects. Well known medicinal plants like Chrysanthemum indicum, Chrysanthemum morifolium, Prunus mume, Myrcia multiflora, Centella asiatica, and Salacia reticulata, Salacia oblonga, and Salacia chinensis exhibited potent AR inhibitory activity. The present review summarizes the list of plant material, and their isolated phytoconstituents which have been tested for their AR inhibitory activity. This litreature review covers the period to 2011, and a total of 72 plants are listed.

Statil suppresses cancer cell growth and proliferation by the inhibition of tumor marker AKR1B10

Aldo-keto reductase 1B10 (AKR1B10) is an oncogenic carbonyl reductase that eliminates alpha,beta-unsaturated carbonyl compounds/lipid peroxides and mediates retinoic acid signaling. Targeted inhibition of AKR1B10 activity is a newly emerging strategy for cancer therapy. This study evaluated the inhibitory activity of a small chemical statil towards AKR1B10 and tested its antiproliferative activity in breast (BT-20) and lung (NCI-H460) cancer cells that express AKR1B10. Experimental results showed that statil inhibited AKR1B10 enzyme activity efficiently, with an IC50 at 0.21¡À0.06 mumol/l. Exposing BT-20 and NCI-H460 cells to statil and diclofenac, a selective AKR1B10 inhibitor, led to dose-dependent inhibition of cell growth and proliferation and plating efficiency. At higher doses (50 mumol/l or higher), statil induced cell death with apoptotic characteristics, such as DNA fragmentation and Annexin-V staining. Furthermore, statil enhanced the susceptibility of cells to acrolein, an active substrate of AKR1B10. Taken together, these data suggest that statil possesses potent antiproliferative activity by inhibiting AKR1B10 activity.

An 18F-Labeled Poly(ADP-ribose) Polymerase Positron Emission Tomography Imaging Agent

Poly(ADP-ribose) polymerase (PARP) is involved in repair of DNA breaks and is over-expressed in a wide variety of tumors, making PARP an attractive biomarker for positron emission tomography (PET) and single photon emission computed tomography imaging. Consequently, over the past decade, there has been a drive to develop nuclear imaging agents targeting PARP. Here, we report the discovery of a PET tracer that is based on the potent PARP inhibitor olaparib (1). Our lead PET tracer candidate, [18F]20, was synthesized and evaluated as a potential PARP PET radiotracer in mice bearing subcutaneous glioblastoma xenografts using ex vivo biodistribution and PET-magnetic resonance imaging techniques. Results showed that [18F]20 could be produced in a good radioactivity yield and exhibited specific PARP binding allowing visualization of tumors over-expressing PARP. [18F]20 is therefore a potential candidate radiotracer for in vivo PARP PET imaging.

Evaluation of the prostaglandin F synthase activity of human and bovine aldo-keto reductases: AKR1A1s complement AKR1B1s as potent PGF synthases

AKR1B1 of the polyol pathway was identified as a prostaglandin F2alpha synthase (PGFS). Using a genomic approach we have identified in the endometrium five bovine and three human AKRs with putative PGFS activity and generated the corresponding recombinant enzymes. The PGFS activity of the recombinant proteins was evaluated using a novel assay based on in situ generation of the precursor of PG biosynthesis PGH2. PGF2alpha was measured by ELISA and the relative potencies of the different enzymes were compared. We identified AKR1A1 and confirmed AKR1B1 as the most potent PGFS expressing characteristic inhibition patterns in presence of methylglyoxal, ponalrestat and glucose.

A recent achievement in the discovery and development of novel targets for the treatment of type-2 diabetes mellitus

Type 2 diabetes (T2DM) is a chronic metabolic disorder. Impaired insulin secretion, enhanced hepatic glucose production, and suppressed peripheral glucose use are the main defects responsible for developing the disease. Besides, the pathophysiology of T2DM also includes enhanced glucagon secretion, decreased incretin secretion, increased renal glucose reabsorption, and adipocyte, and brain insulin resistance. The increasing prevalence of T2DM in the world beseeches an urgent need for better treatment options. The antidiabetic drugs focus on control of blood glucose concentration, but the future treatment goal is to delay disease progression and treatment failure, which causes poorer glycemic regulation. Recent treatment approaches target on several novel pathophysiological defects present in T2DM. Some of the promising novel targets being under clinical development include those that increase insulin sensitization (antagonists of glucocorticoids receptor), decreasing hepatic glucose production (glucagon receptor antagonist, inhibitors of glycogen phosphorylase and fructose-1,6-biphosphatase). This review summarizes studies that are available on novel targets being studied to treat T2DM with an emphasis on the small molecule drug design. The experience gathered from earlier studies and knowledge of T2DM pathways can guide the anti-diabetic drug development toward the discovery of drugs essential to treat T2DM.

Effects of ponalrestat, an aldose reductase inhibitor, on neutrophil killing of Escherichia coli and autonomic function in patients with diabetes mellitus

In diabetic subjects, polyol pathway activity might inhibit neutrophil function and cause nerve damage. The effects of ponalrestat, an aldose reductase inhibitor, were assessed on neutrophil intracellular killing of Escherichia coli and on autonomic function in diabetic subjects in a randomized double-blind, placebo-controlled, crossover trial. We studied 31 diabetic subjects with autonomic dysfunction and 21 age- and sex-matched control subjects. During two 12-wk treatment periods, the diabetic subjects took either 600 mg of ponalrestat or matching placebo once daily. Neutrophil killing of E. coli was measured by a microbiological assay technique. K(max) by neutrophils from the diabetic subjects was lower than in the control group (K(max) of diabetic subjects 54.5 ¡À 26.4 vs. control subjects 67.3 ¡À 16.3, P = 0.045). Ponalrestat significantly increased bacterial killing in the diabetic subjects (K(max) of ponalrestat 75.1 ¡À 16.5 vs. placebo 58.2 ¡À 20.8, P = 0.003) so that there was no longer any significant difference in K(max) between the control subjects and the diabetic subjects on active treatment. Ponalrestat had no significant effect on a range of standard cardiovascular autonomic nerve function tests. We conclude that neutrophil killing of E. coli is impaired in diabetic subjects with autonomic dysfunction. This is restored to normal by ponalrestat.

Polyol pathway and diabetic peripheral neuropathy

This chapter critically examines the concept of the polyol pathway and how it relates to the pathogenesis of diabetic peripheral neuropathy. The two enzymes of the polyol pathway, aldose reductase and sorbitol dehydrogenase, are reviewed. The structure, biochemistry, physiological role, tissue distribution, and localization in peripheral nerve of each enzyme are summarized, along with current information about the location and structure of their genes, their alleles, and the possible links of each enzymes and its alleles to diabetic neuropathy. Inhibitors of pathway enzymes and results obtained to date with pathway inhibitors in experimental models and human neuropathy trials are updated and discussed. Experimental and clinical data are analyzed in the context of a newly developed metabolic model of the in vivo relationship between nerve sorbitol concentration and metabolic flux through aldose reductase. Overall, the data will be interpreted as supporting the hypothesis that metabolic flux through the polyol pathway, rather than nerve concentration of sorbitol, is the predominant polyol pathway-linked pathogenic factor in diabetic peripheral nerve. Finally, key questions and future directions for basic and clinical research in this area are considered. It is concluded that robust inhibition of metabolic flux through the polyol pathway in peripheral nerve will likely result in substantial clinical benefit in treating and preventing the currently intractable condition of diabetic peripheral neuropathy. To accomplish this, it is imperative to develop and test a new generation of “super-potent” polyol pathway inhibitors.
